WILLIAM NELSON RIDDLE, OF CROWLEY, TEXAS.

PUMP-BARREL ATTACHMENT.

To all whom it may concern:

Be it known that 1, WILLIAM NELsoN RIDDLE, a citizen of the UnitedStates, residing at Crowley, in the county of Tarrant and State ofTexas, have invented certain new and useful Improvements in Pump- BarrelAttachments; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to improvements in check valves for pump barrels.

In the general arrangement of valves for pumps it is frequently foundthat scales of iron break off from the pump barrel or pipe and fall tothe bottom of the same, where they sometimes clog up the valve andinterfere with the proper working of the pump.

One of the objects of this invention is to provide a particular form ofvalve provided with a trap arrangement, whereby any dropping scales Wlllnot lnterfere with the working of the valve.

Other objects and advantages-will appear from the following description,and the particular features of novelty will be pointed out moresuccinctly in the claims.

\Vhile the invention is not restricted to the exact details shownanddescribed, still for the purpose of disclosure reference is had to theaccompanying drawings illustrating a practical embodiment of theinvention, in which like letters designate the same parts in the severalviews, and in which- Figure 1 is a longitudinal sectional view through apump barrel provided with my improved valve and trap arrangement. Fig. 2is a detail view of the piston valve and valve rod, and Fig. 3 is'anenlarged detail view of the slotted end nipple of the inlet, with thebearing plug removed.

1 designates a sediment cylinder or barrel provided at its top with areducing member 2 threaded thereon, which reducing member is in turnthreaded with the pump barrel 3 of suitable dimensions. At the lower endthe sediment cylinder is provided with a reducing member 4 of bowlshapedconstruction, provided with a hollow nipple 5 of re stricted diameter.The bowl-shaped member 4 is threaded to the bottom of the cylinder 1,and the nipple 5 is internally screw threaded.

6 designates a hollow dome-shaped member of substantially the sameconstruction Specification of Letters Patent.

Application filed December 28, 1909.

18. the valve casing 13, the slotted end pipe 8 and the intermediatepipe 12, the lower end of the valve spindle being guided through l theaperture in the plug bearing 10, and said 1 spindle extending a shortdistance below the Patented Sept. 13, 1910. Serial No. 535,369.

as the member l, but disposed in an inverted position, the member 6being provided with an internally screw threaded nipple 7 of the samediameter, and adapted to abut against the end of the nipple 5. Threadedthrough these nipples 5 and 7, and securely holding the same together,is an end pipe or nipple 8 slotted at its lower end, as at 9, andprovided with a bearing plug 10 threaded within said lower end andapertured to receivethe spindle of the valve hereinafter referred to.The lower or slotted end of the section 8 is disposed within the hollowdome-shaped member 6, the upper end of the pipe threading with theinternally screw threaded union 11, which in turn is threaded with asecond section of pipe 12 supporting the valve casing. The valve casingis preferably formed by the cylinder 13 having the reducing member 14 atthe bottom thereof threading with the pipe section 12, and said casingbeing provided at its top with a hollow dome-shaped member 15 providedwith a hollow nipple 16 forming a seat for the valve 17 connected withthe valve spindle This valve spindle 18 passes through bottom of theslotted pipe 8 and being provided with the disk 19 to limit the upwardmovement of the valve, but allowing suiticient play for a full flow ofwater there through when elevated.

At 20 there is shown a piston or disk within the valve cylinder, saidpiston or disk being perforated, as at 21, to allow the water to flowtherethrough, and acting as a guiding member for the upper end of thevalve spindle.

The pump barrel is provided with the usual sucker and sucker rod (notshown), and it will be observed that upon operation of the suckerupwardly the valve 17 will be raised from .its seat, allowin the wateror other liquid to pass upwardl y through the pipes 8, 12 and valvecasing 13, an upon the down stroke the valve 17 is closed by thepressure above and the weight of the valve and its stem.

It will thus be observed that should any iron scale fall down throughthe pump barrel the same will fall to the bottom of the sediment chamber1, in a position so far below the valve proper that it will not in anyway interfere with the operation of the valve.

Having thus described the invention, what I claim is 1. An attachmentfor the lower end of pump barrels, comprising a sediment chamber havinga downwardly disposed bell or dome-shaped member, a fluid inlet conduitterminating at its lower end within said bell and at its other endprojecting upwardly within said sediment chamber, a valve controllingsaid inlet conduit, means guiding said valve and means limiting itsmovement, substantially as described.

2. An attachment vfor the lower end of pump barrels, comprising asediment chamber, a fluid inlet conduit extending through the lower endof said chamber and projecting upwardly therein, a valve casingsurmounting said fluid inlet conduit, a valve mounted on said valvecasing, a valve spindle extending through said casing and said fluidinletjconduit, said valve spindle normally projecting below said fluidinlet conduit and being provided at its lower end with a stop disk, andbeing also provided with a perforated guiding disk within the valvecasing, substantially as described.

3. An attachment for the lower end of pump barrels, comprising asediment chamber having a downwardly disposed bell or dome-shapedmember, a fluid inlet conduit terminating at its lower end within saidbell and having slots opening therein and an apertured bearing plug, theother end of said conduit projecting upwardly within said chamber, avalve controlling said conduit, a spindle connected to said valve andextending downwardly through said apertured plug and normallyterminating a short distance below same, said spindle at its lower endbeing provided with a stop disk, substantially as described.

4. An attachment for the lower end of pump barrels, comprising anenlarged sediment chamber connected with the pump barrel, and at itslower end provided with a restricted hollow nipple internally screwthreaded, a dome-shaped member provided with an internally screwthreaded nipple alining with said first mentioned nipple, a pipethreading through said nipples and extending upwardly within saidsediment chamber, said pipe being provided at its lower end with slotsand With an apertured bearing plug, the lower end of said slotted pipeextending downwardly within said dome-shaped member, a valve casingwithin said sediment chamber, an intermediate pipe between said valvecasing and said slotted pipe for supporting said valve casing in aposition substantially at the top of said sediment cylinder, said valvecasing being open at its upper end providing a valve seat, a valvespindle passing through said casing, said slotted pipe, intermediatepipe and apertured bearing plug, a perforated bearing disk carried bysaid spindle within said valve casing, a. valve disk connected to thetop of said spindle, and a stop disk connected to the bottom of saidspindle, sub

stantially as described.

In testimony whereof, I affix my signature, in presence of twowitnesses.
